Wheat inputs experiment locations
Aims

To assess if the previous year's results from this experiment could be replicated in a year with average to above average growing season rainfall (GSR).

Key messages
  • In high rainfall years, 70 plants /m2 will produce lower yields than crops with higher plant numbers, unless some nitrogen is applied at the five-leaf stage (GS 15).
  • If nitrogen is applied at GS 15, similar yields can be obtained.
  • There may be opportunities to use phosphours in crop to maximise yields.
  • More work needs to be carried out to confirm this.
  • Lower than optimal tiller numbers can still produce acceptable yields and water use efficiencies (WUE) in wet years.
